DETAILED DESCRIPTION

An image capturing lens assembly includes, in order from an object sideto an image side, a first lens element, a second lens element, a thirdlens element, a fourth lens element, a fifth lens element, and a sixthlens element. The image capturing lens assembly has a total of six lenselements with refractive power.

The first lens element has negative refractive power, so that it isfavorable for enlarging the field of view to capture more of the imagescene. The first lens element can have an object-side surface beingconvex in a paraxial region thereof and an image-side surface beingconcave in a paraxial region thereof, so that it is favorable forreducing the astigmatism.

The second lens element can have an object-side surface being concave ina paraxial region thereof and an image-side surface being convex in aparaxial region thereof. Therefore, it is favorable for correcting theastigmatism.

The fourth lens element has positive refractive power. Therefore, it isfavorable for reducing spherical aberration.

The fifth lens element with negative refractive power can have anobject-side surface being concave in a paraxial region thereof and animage-side surface being convex in a paraxial region thereof. Therefore,it is favorable for improving the resolving power. Moreover, theimage-side surface of the fifth lens element can have at least oneinflection point in an off-axis region thereof; therefore, it isfavorable for effectively reducing the incident angle of the off-axis onthe image plane so as to improve the responding efficiency of the imagesensor.

The sixth lens element can have an object-side surface being convex in aparaxial region thereof and an image-side surface being concave in aparaxial region thereof. Therefore, it is favorable for the principalpoint being positioned away from the image plane so as to reduce thetotal track length of the image capturing lens assembly. In addition,the image-side surface of the sixth lens element has at least oneinflection point in an off-axis region thereof, so that it is favorablefor correcting the image distortion in a peripheral region thereof andimproving the relative illumination.

When a focal length of the image capturing lens assembly is f, and acurvature radius of the image-side surface of the sixth lens element isR12, the following condition is satisfied: 0.25<f/R12<1.25. Therefore,it is favorable for reducing the back focal length of the imagecapturing lens assembly.

When a focal length of the first lens element is f1, and a curvatureradius of the object-side surface of the second lens element is R3, thefollowing condition is satisfied: |f1/R3|<1.4. Therefore, it isfavorable for improving the illumination.

When a focal length of the second lens element is f2, and a focal lengthof the third lens element is f3, the following condition is satisfied:|f2/f3|<2.0. Therefore, it is favorable for balancing the refractivepowers of the second and the third lens elements so as to correct theaberration.

When a maximal field of view of the image capturing lens assembly isFOV, the following condition is satisfied: 120 deg.≤FOV<200 deg..Therefore, the image capturing lens assembly can have larger field ofview so as to obtain more of the image scene.

When the focal length of the first lens element is f1, the focal lengthof the second lens element is f2, and the focal length of the third lenselement is f3, the following condition is satisfied:|f1/f2|+|f1/f3|<1.0. Therefore, it is favorable for balancing therefractive powers of the image capturing lens assembly.

When an axial distance between the image-side surface of the sixth lenselement and an image plane is BL, and the focal length of the imagecapturing lens assembly is f, the following condition is satisfied:BL/f<1.0. Therefore, it is favorable for maintaining a proper back focallength.

When a curvature radius of the object-side surface of the sixth lenselement is R11, and the curvature radius of the image-side surface ofthe sixth lens element is R12, the following condition is satisfied:−0.40<(R11−R12)/(R11+R12)<0.40. Therefore, it is favorable foreffectively correcting the astigmatism.

According to the image capturing lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the image capturing lensassembly may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than spherical surface so as to have more controllablevariables for eliminating the aberration thereof, and to furtherdecrease the required number of the lens elements. Therefore, the totaltrack length of the image capturing lens assembly can also be reduced.

According to the image capturing lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to the opticalaxis, and the off-axis region refers to the region of the surface wherelight rays travel away from the optical axis. Particularly, when thelens element has a convex surface, it indicates that the surface isconvex in the paraxial region thereof; when the lens element has aconcave surface, it indicates that the surface is concave in theparaxial region thereof.

According to the image capturing lens assembly of the presentdisclosure, the image capturing lens assembly can include at least onestop, such as an aperture stop, a glare stop or a field stop. Said glarestop or said field stop is for eliminating the stray light and therebyimproving the image resolution thereof.

According to the image capturing lens assembly of the presentdisclosure, an aperture stop is configured as a middle stop. The middlestop disposed between the first lens element and the image plane isfavorable for enlarging the field of view of the image capturing lensassembly and thereby provides a wider field of view for the same.

According to the present disclosure, an image capturing device isprovided. The image capturing device includes the image capturing lensassembly according to the aforementioned image capturing lens assemblyof the present disclosure, and an image sensor, wherein the image sensoris disposed on or near an image plane of the aforementioned imagecapturing lens assembly. In some embodiments, the image capturing devicecan further include a barrel member, a holding member or a combinationthereof.
